WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 747,513, dated December22, 1903. v

I Application filed September 16, 1903. Serial No.173A57. (No model-l Toall whom it may concern:

Be it known that I, PRESTON P. TOWNSEND a citizen of the United States,residing at Whiteburg, in the county of Worcester and State of Maryland,have invented a new and useful Wheel-Plow, of which the followingis aspecification.

This invention relates to a wheelplow and it has for its object toprovide a device of this class which shall possess superior advantagesin point of simplicity, durability, ease of operation, and generalefficiency.

With these ends in view my invention comprises a frame structuresupported upon wheels and provided with a laterally-adjustable carrierwhich is connected adjustably with the beam extending rearwardly fromthe plow-standard, which is thereby pushed in a forward direction bythetraction applied to the plow-frame.

The invention further comprises means whereby the plow may be raisedfrom or set into the ground and retained securely at any position towhich it may be adjusted.

Theinvention further consists in means for maintaining the plow in itsproper position when adjusted laterally by means of the carrier.

The invention further consists in improved traction means applied to theframe structure and in other details of construction which will behereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of awheel-plow constructed in accordance with the principles of myinvention. Fig. '2 is a transverse sectional View taken verticallythrough the plow in front of the adjusting-slide, Fig. 3 is a sectionaldetail view taken longitudinally through the adjustable carrier andrelated parts. Fig. 4 is a sectional detail view taken through the axleand the traction means.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

The frame of my improved wheel-plow is composed, essentially, of sidebars 1 1, connected at their front ends by-cross-bars'2 2, secured tothe upper and lower sides of said side bars. The rear ends of the latterare connected by means of cross-bars 3 3, which likewise are placedagainst the upper and lower sides of the side bars of the frame. Thelatter is provided with a longitudinal brace-beam 4, the ends of whichare made fast between the front and rear cross-bars 2 2 and 3 3, and thesaid longitudinal beam is reinforced by a cross-piece 5, which spacesthe side pieces 1 1 and which is provided with a notch or recess 6 inits under side for the reception of the longitudinal brace-beam.

7 designates the axle, which is placed upon the upper part of the frameslightly in front of the cross-piece 5 and which is provided at its endswith rearwardly-extending cranks 8, which are supported uponthecross-pieces 1. The rear ends of the cranks 8 are bent outwardlytoform the spindles 9, upon which thetraction-wheels 10 are revolublymounted.

11 designates a block which constitutes the plow-carrier and which isprovided in its rear side with a recess 12, including the upper andlowerrear cross-bars 3 of the frame. Clipplates 12*, which are disposedagainst the rear edges of the rear cross-bars, are connected by means ofbolts 14; with the carrier 11, said bolts extending through the spacebetween the upperand lower cross-bars 3, upon which by loosening thesaid bolts the said carrier may be conveniently adjusted laterally inthe space between the longitudinal brace-beam and the adjacent side bar1 of the frame. The carrier 11- is provided with upwardly-extending lugs15, between which is pivotally mounted a lever 16, which extendsforwardly beyond the cross-bar 5.

17 designates the ploW-standard,which carries at its lower end thelandside 18 and point 19, which latter has the upwardly-extending colteror cutting edge 20. Between the point and the colter or cutting edge isthus formed a recess in which the moldboard 21 is firmly secured, saidmoldboard being also fitted to and connected with the standard 17. Apair of shanks 22 are connected at their lower ends, respectively, withthe landside 18 and with the moidboard 21, and said shanks at theirupper ends areconnected bya crosspiecev 23, which is disposed in aboutthe same ard 17.

24 designates a short beam, the front end of which is bolted to orotherwise connected with the upper end of the standard. Said beam isalso connected with the cross-piece 23, connecting the upper ends of theshanks 22 by means of a clip 25. The upper end of the shank has atransverse groove 26, in which below the front end of the beam 24 islocated a link 27, the upper end of which engages the upper side of thelever 16, which latter extends through the said link and is connectedtherewith by means, such as a staple 28, which will not interfere withthe free vibration of said link. The rear end of the plow-beam has abracket 29, constructed, preferably, of metal and adapted to engage anyone of a plurality of perforations 30 in' the front side of the carrier11. The perforations 30 while of sufficient size to receive the bracket29 will not admit the rearend of the plow-beam, upon which the saidcarrier thus exercises a pushing action in a forward direction when themachine is in operation.

The standard 17 of the plow is provided in its rear side with a verticalrecess3l, extending to the top of said standard and adapted to receive alip 32, extending downwardly from the slide 33, which is mounted insuitable keepers 34in the upper sides of the longitudinal brace-beam 4and upon one of the side bars of the frame. The keepers 34 may beprovided with set-screws 35, whereby the slide 33 may be retained in anyposition to which it may be adjusted. This slide serves to hold thestandard of the plow steady during the operation of the device bypreventing lateral displacement thereof either to the right or to theleft and also by bearing or pushing in a forward direction upon the saidstandard.

The upper front cross-bar 2 together with the transverse brace 5 of theframe support a plate 36, upon which is mounted a segmentrack 37, whichis supported by a curved brace 38.

The traction device of my improved plow includes a clip consisting oftwo members 39 and 40, clamped upon the axle 7 by means of screws orbolts connecting the said members. The front member 39 is extendeddownwardly and has a plurality of perforations41.

42 designates the tongue, which is provided at its rear end with adepending flange 43, having a perforation through which passes a bolt44, which may be extended through any one of the perforations 41,thereby connecting the rear end of the tongue adjustably with the clip39. The tongue extends between the front frame members 2 2, beingloosely connected With the same by means of a vertical pin or bolt 45.The tongue 42 supports an upright 46, at the upper end of which ismounted an operatinglever 47, equipped with a spring-actuated lock-dog48, engaging the segment-rack 37. The lever 47 has a downwardlyextendingbracket 49,

which is connected by means of-a pivoted link 50 with the front end ofthe rocking lever 16.

A pair of bars 51, secured to the inner sides of the side beams 1 1,near the front ends of the latter, support a seat 52, said seat-barsbeing in turn supported upon the cross-bars 5 of the frame.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my improved wheel-plowwill be readily understood. The traction of the draft, as will bereadily seen, is applied directly to the axle, which being firmlyconnected with the frame serves to move the latter in a forwarddirection upon the transporting-wheels. The carrier-block 11, supportedupon the rear cross-bars of the frame, will thus push in a forwarddirection upon the rear end of the plow-beam, and the depending lip 32of the slide-bar 33 by engaging the standard will serve not only tosteadythe latter, but also to assist in pushing it and the plow in aforward direction. This method of propelling the plow will have adistinct tendency to prevent the nose or point of the plow from startingin an upward direction, and by properly adjusting the rear ends of thebeam with relation to the openings 30 in the block 11 the ends or pointmay be pointed slightly in a downward or upward direction or maintainedin a perfectly level position, as maybe desired. The rear end of theplow-beam may also be shifted from one to another of said openings whenthe plow is raised or lowered for the purpose of engaging the ground ata less 'or greater depth. When it shall be desired to elevate the plowfrom the ground, this may be easily accomplished by manipulating thelever 47, the lock-dog of said lever having been previously disengagedfrom the segment-rack 37. Owing to the extensive leverage, the operationof raising or lowering said plow may be effected with great facility,and in consequence thereof the plow is under the easy and perfectcontrol of the driver. Lateral adjustment of the plow with relation tothe draft may be readily effected by simply moving the carrier 11 andthe slide 33 in either direction. The traction is likewise capable ofadjustment by properly adjusting the clip 39 40 upon the axle.

I have in the foregoing described a simple and preferred construction ofmy improved wheel-plow, and I desire it to be understood that I do notnecessarily limit myself to the precise structural details herein setforth, but reserve the right to any changes, alterations, andmodifications which may be resorted to within the scope of my inventionand without departing from the spirit or sacrificing the utility of thesame.
